bootster Posted November 30, 2005 Share Posted November 30, 2005 I have converted a Benelli Super 90 from a tactical configuration to a rifled slug gun. It went from a 18.75" open sight bbl to a 24" heavy fully rifled slug bbl with a scope drilled and tapped to the reciever. I would say that I added maybe three lbs. to the gun. It misfires all the time and I have done everything I know of to fix it,including adding a "sure cycle" recoil spring unit. My question is this;do I need a heavier recoil spring than the one that comes with the tactical configuration or "sure cycle"? This gun is about 15 years old. Any advice would be appreciated.
